Momo Chen is a quiet and shy girl with Jia Sen as her only friend. She is often forgotten and left behind. Her only interest is to read her manga, "Prince Kashaba." Mars is a superstar whose popularity went downhill after a series of negative publicity incidents. His finances, as a result, go into red alert and he is forced to move out of the company house provided to him and moves into a cheaper place instead. He is also told to attend school while on down time.
On the first day of school for Mars, he arrogantly signs his name onto one of Momo's manga with a permanent marker over a picture of Prince Kashaba. Momo becomes furious and yells at him in front of everyone. Meanwhile, Mars' manager, Yi Zhi, finds him a room for rent in Momo's house. Momo is unaware that the room is being rented until her sister drops the news on her suddenly after school. Both are unaware that it is Mars who is to be their tenant.
Mars gradually befriends Momo and her childhood friend Jia Sen, a swimming captain with the cognitive ability and maturity of an 8-year-old. Momo Chen describes him as "different from us" and "not silly or stupid". Jia Sen earns many medals for swimming and gives them to Momo because he secretly has feelings for her. He refers to Mars as "bad guy" and often gets upset when Momo hangs out with Mars. In the beginning Mars and Momo constantly fight but after going through some challenges together, they finally begin to show their feelings for one another.
